Watch for one flight trending up over time —
an early sign of a cylinder issue.
A slow drift can indicate injector or induction changes.
v7.5: Low fuel pressure under load is the first
sign of a fuel pump or supply problem — track this trend.
Max cylinder-to-cylinder EGT difference. A widening
spread points to an injector or induction imbalance.
Rapid cooling on descent (shock cooling) stresses
cylinders. Sustained high values are worth a closer look.
Injector balance. Lower is better; a rising trend
suggests injectors due for cleaning.
A downward drift in cruise oil pressure can be an
early sign of pump wear or a developing oil-system issue.
